Patented Apr. 24, 1945 UNITED STATES om CE 1 Claim.

The present invention relates to new and useful improvements in display devices of the double reel and web type for use particularly by children, and has for its primary object to provide, in a manner as hereinafter set forth, novel means for teaching stories, et cetera, through the medium of a series of pictures on a strip or Web of suitable flexible material.

Other objects of the invention are to provide a display device of the aforementioned character which will be comparatively simple in construction, strong, durable, compact, attractive in appearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a top plan view of a display device constructed in accordance with the present invention.

Figure 2 is an elevational View, looking at one side of the device.

Figure 3 is an elevational view, looking at the opposite side of the device.

Figure 4 is a perspective view of one of the spools.

Figure 5 is a detail view in perspective of the operating key.

Figure 6 is a top plan view of the device with the cover removed.

Figure '7 is a view in longitudinal section, taken substantially on the line 11 of Figure 6.

Figure 8 is a cross sectional view, taken substantially on the line 8-8 of Figure 6.

Figure 9 is a fragmentary view in vertical section, taken substantially on the line 9-9 of Figure 8.

Figure 10 is a bottom perspective view of a corner portion of the cover.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a substantially rectangular case of suitable dimensions and material which is designated generally by reference numeral I. The case I includes a bottom 2, sides 3, ends 4 and a cover 5, said cover 5 having a window 6' therein.

One of the side walls 3 has formed in its inner face, adjacent its ends, recesses or pockets 6 which extend downwardly thereinto from the upper edge thereof. The other side wall 3 of the case I has formed therein openings I which are transversely aligned with the recesses 6.

Removable spools 8 and 9 are mounted transof the spools 8 and 9. The trunnions II have 7 formed therein slots I2 for the reception of a turning key I3.

A web I4 of suitable material is carried by the spool 8-. The web I4 is connected at one end, as at I5, to the empty spool 9 for winding thereon. In the embodiment shown, the web I4 is provided with a series of pictures I6 to be viewed through the window 6. Transverse guides I! in the upper portion of the case I support the web I4 adjacent the window 6'. An insulated opening I8 is provided in the bottom 2 of the case I. The opening I8 accommodates a conductor cord I9 to an electric lamp 20 in the case I if it is desired to illuminate the pictures on the web I4.

Depending bearings 2| are provided on one of the longitudinal marginal portions of the cover 5 for engagement in the recesses -6 for retaining the trunnions ID in position therein. The bearings 2| also provide means for assisting in retaining the cover 5 in position on the case I. A suitable securing latch 22 is provided on the other side portion of the cover 8 for connection with the corresponding side wall of the case I.

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Briefly, the case .I is opened to permit the mounting therein of the spools 8 and 9, the former having wound thereon the web I4. The web I4 is carried across the guides l1 and connected at I5 to the spool 9, after which the case I is closed. Through the medium of the key I3, the spool 9 is turned to wind the web I4 thereon from the spool 8. Thus, the pictures I6 may be successively viewed in an attractive, impressive manner through the window 6. When the web I4 has been exhausted, it may be rewound on the spool 8 by connecting the key I3 to said spool. The construction and arrangement is such that the spools 8 and 9 may be expeditiously inserted and removed.

It is believed that the many advantages of a display device constructed in accordance with the present invention will be readily understood,

and although a preferred embodiment of said device is as illustrated and described, it is to be understood that changes in the details of'construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is: v i In a display device of the character described, a substantially rectangular case including a, bottom, sides, ends and a removable fiat cover, one of said sides having, in its inner face, recesses extending downwardly thereinto from the upper edge thereof, the other of said sides having openings therein, a pair of spools removably mounted in the case and including trunnions on their ends journaled in the recesses and the openings, and bearings depending from the cover adjacent but inwardly of one side edge thereof and engaged in the recesses for retaining the respective trunnions therein.
